Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

These boards provide, 2, 4, 8, 16, or 32 +high-speed serial ports or modems. This driver supports up to a combination +of four RocketPort or RocketModems boards in one machine simultaneously. +This file assumes that you are using the RocketPort driver which is +integrated into the kernel sources. + +The driver can also be installed as an external module using the usual +"make;make install" routine. This external module driver, obtainable +from the Comtrol website listed below, is useful for updating the driver +or installing it into kernels which do not have the driver configured +into them. Installations instructions for the external module +are in the included README and HW_INSTALL files. + +RocketPort ISA and RocketModem II PCI boards currently are only supported by +this driver in module form. + +The RocketPort ISA board requires I/O ports to be configured by the DIP +switches on the board. See the section "ISA Rocketport Boards" below for +information on how to set the DIP switches. + +You pass the I/O port to the driver using the following module parameters: + +board1 : I/O port for the first ISA board +board2 : I/O port for the second ISA board +board3 : I/O port for the third ISA board +board4 : I/O port for the fourth ISA board + +There is a set of utilities and scripts provided with the external driver +( downloadable from http://www.comtrol.com ) that ease the configuration and +setup of the ISA cards. + +The RocketModem II PCI boards require firmware to be loaded into the card +before it will function. The driver has only been tested as a module for this +board. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +INSTALLATION PROCEDURES +----------------------- + +RocketPort/RocketModem PCI cards require no driver configuration, they are +automatically detected and configured. + +The RocketPort driver can be installed as a module (recommended) or built +into the kernel. This is selected, as for other drivers, through the `make config` +command from the root of the Linux source tree during the kernel build process. + +The RocketPort/RocketModem serial ports installed by this driver are assigned +device major number 46, and will be named /dev/ttyRx, where x is the port number +starting at zero (ex. /dev/ttyR0, /devttyR1, ...). If you have multiple cards +installed in the system, the mapping of port names to serial ports is displayed +in the system log at /var/log/messages. + +If installed as a module, the module must be loaded. This can be done +manually by entering "modprobe rocket". To have the module loaded automatically +upon system boot, edit the /etc/modprobe.conf file and add the line +"alias char-major-46 rocket". + +In order to use the ports, their device names (nodes) must be created with mknod. +This is only required once, the system will retain the names once created. To +create the RocketPort/RocketModem device names, use the command +"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero. For example: + +>mknod /dev/ttyR0 c 46 0 +>mknod /dev/ttyR1 c 46 1 +>mknod /dev/ttyR2 c 46 2 + +The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes) +for you: + +>/dev/MAKEDEV ttyR + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +ISA Rocketport Boards +--------------------- + +You must assign and configure the I/O addresses used by the ISA Rocketport +card before installing and using it. This is done by setting a set of DIP +switches on the Rocketport board. + + +SETTING THE I/O ADDRESS +----------------------- + +Before installing RocketPort(R) or RocketPort RA boards, you must find +a range of I/O addresses for it to use. The first RocketPort card +requires a 68-byte contiguous block of I/O addresses, starting at one +of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h, +0x300h, 0x340h, 0x380h. This I/O address must be reflected in the DIP +switiches of *all* of the Rocketport cards. + +The second, third, and fourth RocketPort cards require a 64-byte +contiguous block of I/O addresses, starting at one of the following +I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h, +0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h. The I/O address used by the +second, third, and fourth Rocketport cards (if present) are set via +software control. The DIP switch settings for the I/O address must be +set to the value of the first Rocketport cards. + +In order to destinguish each of the card from the others, each card +must have a unique board ID set on the dip switches. The first +Rocketport board must be set with the DIP switches corresponding to +the first board, the second board must be set with the DIP switches +corresponding to the second board, etc. IMPORTANT: The board ID is +the only place where the DIP switch settings should differ between the +various Rocketport boards in a system. + +The I/O address range used by any of the RocketPort cards must not +conflict with any other cards in the system, including other +RocketPort cards. Below, you will find a list of commonly used I/O +address ranges which may be in use by other devices in your system. +On a Linux system, "cat /proc/ioports" will also be helpful in +identifying what I/O addresses are being used by devics on your +system. + +Remember, the FIRST RocketPort uses 68 I/O addresses. So, if you set it +for 0x100, it will occupy 0x100 to 0x143. This would mean that you +CAN NOT set the second, third or fourth board for address 0x140 since +the first 4 bytes of that range are used by the first board. You would +need to set the second, third, or fourth board to one of the next available +blocks such as 0x180. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +RocketPort and RocketPort RA SW1 Settings: + + +-------------------------------+ + | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | + +-------+-------+---------------+ + | Unused| Card | I/O Port Block| + +-------------------------------+ + +DIP Switches DIP Switches +7 8 6 5 +=================== =================== +On On UNUSED, MUST BE ON.
